Day 127: Sedimentary Rocks
By Mr. G on Mar 5, 2008 in Geology, Featured
Sedimentary rocks are those that are formed by the compaction and cementation of fragments of other rocks: sand, gravel, and other rock segments. In today’s class, students completed the Sedimentary Rocks Notes Guide in class as a means of understanding the formation, texture, and composition of sedimentary rocks. We then watched a brief (4-minute) video clip about the formation of the Grand Canyon - a huge area of sedimentary rocks.
Tomorrow we’ll tackle the final of the three rock types: Metamorphic rocks. We’ll also complete a quiz over the three rock types and their identifiable properties.
Homework: Review rock types for upcoming quiz.
